CARACAS, Venezuela (AP) — Venezuela became a country mostly without cash on Friday, sparking scattered protests and looting around the country as people fumed at having their already limited purchasing power cut off almost entirely.

As the nation’s most widely used banknote went out of circulation, the higher-denomination bills that were supposed to replace the 100-bolivar note had not yet arrived at banks or ATMs. That forced people to rely on credit cards and bank transfers or to try to make purchases with bundles of hard-to-find smaller bills often worth less than a penny each.

Indignation at having to deal with an economy even more paralyzed than usual sparked social unrest. Police put down looting near a bank building in the large western city of Maracaibo with several arrests. Young men marched down the street after growing tired of waiting outside the bank to turn in their money. They waved their 100-bolivar bills in the air and chanted “they’re useless”, then turned and ran as police in full riot gear began firing tear gas canisters.

Mobs looted several businesses in the remote eastern state of Bolivar. In total, authorities said there were protests and looting in six cities, leading to 32 people being detained and one injured.

In Caracas, some people passed the day banging on pots and cursing the government’s apparent lack of planning. There was no cash to be seen changing hands on the street or inside shops, and no sign that the new bills were on their way.

President Nicolas Maduro made a surprise announcement Sunday that the 100-bolivar note would go out of circulation by the week’s end amid the world’s highest inflation. He also temporarily closed the border with Colombia and Brazil, and then on Thursday night extended the border closure for another 72 hours.

Maduro said the closure was needed to thwart “mafias” who hoard bolivars. Critics mocked the notion that gangsters would choose to keep their wealth in the world’s fastest-devaluing currency. The 100-bolivar bill – until now the country’s largest denomination – is worth little more than 2 cents, down from 10 cents at the start of the year.

The embattled president held up a new 500-bolivar bill on his television show Thursday, promising the new banknotes would soon be in wide circulation and offering to temporarily cut sales tax for credit card transactions. But on Friday, ATMs were still issuing only the now-worthless 100-bolivar notes.

Maduro also said the government has begun to circulate new 100- 50- and 10-bolivar coins, but few seem to have reached the public.

On Friday, Maduro said the ploy to undermine the criminals had worked.

“We’ve burned the mafia’s hands,” he said. “That there were some difficulties, and that there may be some difficulties going forward was inevitable.”
